What si unit replaces pound

When does resonance occur? when the frequency of a forced vibration equals the natural frequency when the frequency of a forced vibration is greater than the natural frequency when two waves of the same frequency interfere when two waves of slightly

As its speed increases, what happens to its energy of motion?

What happens to the density of a gas when it is compressed? - the density does not change -the density increases -the density decreases

Explain how wavelength and frequency are important when determining the type of light.

Suppose that you had an electrically charged stick. If you divided the stick in half, each half would have half the original charge. If you split each of these halves, each piece would have a quarter of the original charge.

Technician a says that when measuring a rotor's thickness variation, you should measure the rotor in a minimum of five to eight places around the face of the rotor.

What acceleration will you give to a 25kg box if you push it with a force of 85N

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. assume that the rate of charge flow in a lightning bolt is about 24000 c/s and this lasts for 105 µs or less.
